The motivation and methodology for measuring intelligence have changed repeatedly in the modern history of large-scale student testing. Test makers have always sought to identify raw aptitude for cultivation, but they have never figured out how to promote excellence while preserving equality. They've settled for egalitarianism, which gives rise to "culturally fair" tests that substitute vagaries for knowledge, deprive students of any real appreciation for language, and trivialize education. Robert Jackson yearns for traditional oratorical approaches to schooling that venerate and imitate essential, time-tested masters. Unfortunately, he writes, such an education defies measurement with today's multiple-choice instruments. (Contains 2 footnotes.)
